Answer:
m = 10 , n = 5
Step-by-step explanation:
using the cosine and tangent ratio in the right triangle and the exact values
cos45° =
and tan45° = 1 , then
cos45° =
=
=
( cross- multiply )
m = 5
×
= 5 × 2 = 10
-----------------------------------------
tan45° =
=
= 1 , then
n = 5
5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
Should be the second one.
